Well after properly timing the new cam in my TBI 350 in the 1983, I am leaving it alone for some time. It is running GREAT, pulls hard, smooth, and fast.

Well I am pulling back on the TBI projects for a little while. Time for a Cammed/Head LQ4 swap/4L80E (2006 Express 2500 with 6K miles). This time into a very clean 1995 G20 Shorty Conversion Van (Garage kept with 65,000 miles but a lame, weak 4.3 TBI).

Laying in the corner of my garage is my 2006 LQ4 6.0. It started out with 340 HP and is getting a 224/224 @ .050 cam, a 2,600 rpm stall torque converter, long tube headers, and HP tuning software to tune it with.

 

Since you mentioned the 4L80E, I got a question that you might be able to answer. My dad and I pulled a L31 with what I believe is a 4L80E out of a wrecked 99 Express 3500. What I'd like to know is the 4L80E A direct bolt in in a F-Body? Sorry to hijack the thread wiht this question.

 

No if it is the 4L80E, it is not a direct bolt-in. The 4L60E would be a direct bolt-in fit. The 4L80E will take some massive transmission tunnel massaging to clear.

 

Thanks man! I guess if I ever get my hand son the engine it's gonna be either a 4L60 or a T5. Maybe even a T56...



Now, Back to your regularly scheduled TGO thread.

 

Man, you always have some neat things lying around. That'll make for a mean swap. Shame the engine and more importantly the trans are so big. In a bare bones third gen or something, that would make for a real fast setup.

 

Careful with that software. Ive seen some errors and tables that shouldnt be touched in their package when I was milling around on their boards. Take it with a grain of salt before diving into a table or something.
